OPL-40M


The OPL-40M, also known as the SPL-40, is an under-barrel grenade launcher developed by the Z111 Factory in Thanh Hóa, Vietnam.

History

The OPL-40M was developed and produced by Z125 Factory of General Department of Defence Industry.
The OPL-40M was first shown in the Indo Defence 2018 exhibit which represents a step forward in Vietnam's effort to localize its defense industry.

Design

The OPL-40M is chambered in standard 40×46mm NATO rounds, enabling compatibility with international ammunition standards. Its design draws inspiration from the M203, GL40, and GP-25,integrating the advantages of these systems to meet the operational requirements of the Vietnamese military.
The OPL-40M is designed to be mounted under assault rifles, including Kalashnikov rifles and STV rifles - Vietnam’s new standard service rifles based on the Israeli Galil ACE platform. This grenade launcher can be mounted under the STV-380 using the STV-380’s picatinny rail and bayonet lug.
The OPL-40M uses a forward-sliding and tilting barrel mechanism, allowing for the loading of longer grenade rounds.

Adoption

The OPL-40M is a domestically produced launcher intended to replace earlier imported grenade launchers such as the M79, and other foreign designs like the M203 and GP-25.
